Hello. I'm new here, and I have what I hope is a do-able query.

I want to be able to work out the date a certain number of working days before another date. For example: What is the date 11 working days before the 28th of a particular month?

I've had a play with networkdays, but it's all getting a bit convoluted and abstract. Is there anyone out there who can easily crack this one for me, formula-wise? I'd be massively grateful.
